Unlike other iPod software to copy songs off the iPod, iPod.iTunes does real add-synchronization, even in two directions if desired. iPod.iTunes evaluates the source for songs, podcasts, videos and/or playlists that are not in the target and only adds these seamlessly, avoiding duplicates, saving your time. Unlike iTunes' "auto update/sync" function iPod.iTunes generally does not delete content in the target. iPod.iTunes can also transfer song dependend data like "My Rating", "Last Played", "Play Count", and album artwork.
